2 Claims.

My invention relates to a jacket for bottles containing materials. such as vitaminized milk. subject to deterioration or loss of efiicacy upon exposure to light; and the broad object of my invention is to provide improved means for shielding the bottle contents from light.

Another object is to provide a jacket which closely embraces the bottle, so that the jacketed bottle requires substantially no more room than the bottle itself, and whereby the bottles may be handled and carried in ordinary crates in the usual manner.

Another object is to provide -a jacketed bottlei from which contents may be poured without removing the jacket.

Still another object is to provide a jacket having improved means cooperating with the bottle to provide a closure at the top-of the jacket.

The invention possesses other objects and features of advantage. some of which, with the foregoing, willbe set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claims.

Referring to the drawing:

Figure l is a side view, partly in section and partly in elevation, showing my improved jacket about a milk bottle; and

Figure 2 is a plan view of the same, also partly in section.

Figure 3 is a plan view on somewhat smaller scale of the flat blank from which the jacket is folded.

Figure 4 is a fragmentary sectional view showing the upper portions of a modified jacket.

In terms of broad inclusion. my bottle jacket comprises a casing for receiving the bottle, and means on the casing and cooperating with the bottle neck to provide a closure; whereby a snugly fitting jacket is provided to shield the bottle contents from light, and whereby the contents "may be poured from the bottle without remov- The stresses set up by this outward bowing serve to frictionally hold the jacket in place. The prismatic shape also provides considerable room for transverse expansion to take care of variations in bottles which seldom run true to size.

The casing is folded from the generally rectangular blank illustrated in Figure 3 having a series of parallel crease lines I dividing the blank into wall panels I. A narrow sealing flap 8 is provided at one end of the blank, adapted to be adhesively united to the wall panel at the opposite end' to form the tubular casing. Any suitable non-transparent sheet material may be employed for making the blank.

Means cooperating with the bottle neckare arranged on the casing to provide a closure. For this purpose a plurality of closure flaps 9 are foldably connected to the upper edges of wall panels 8. adapted to extend inwardly and engage under neck flange 3. These flaps are shaped and proportioned to abut along adjacent edges when the flaps are folded to horizontal positio thus forming a light-tight collar about the bottle neck. Figure 3 shows the tapered'fiaps laid out fiat; and Figure 2 illustrates how the unfolded flaps register to. form the closure. The inner ends of the flaps define an opening through.- which the bottle neck extends; and the flap ends are preferably curved to provide a circular aperture closely fitting the neck under flange 3.

With such a closure the jacket may readily be applied by slipping the bottomless sleeve down over the bottle and then folding flaps O inwardly to engage the neck under the flange. The closure flaps are thus securely locked in place, and additionally function to hold the jacket in use position. A bottle with my improved jacket takes up substantially no more room than the bottle itself, and the jacketed bottles may be handled and carried in ordinary bottle crates in erally conical shape to facilitate the pouring operation.

I claim:

1. A jacket for a bottle, circular in cross section, having a neck, comprising a light-proof prismatic cardboard casing, having an open lower end, the small diameter or said casing being less than the diameter oi said bottle, to resiliently retain it on the bottle and the length of said casing being less than the length of said bottle, and unconnected integral substantially trapezoidal flaps having their lateral edges converging toward their free ends and hinged on the casing at the upper end thereof to provide a light-proof closure extending directly from the edge of the casing to the neck of said bottle and in contact therewith.

2. A jacket for a bottle, circular in cross section. having a neck and an annular flange therearound, comprising a 1ight-proo1 prismatic cardboard casing, having an open and lower end, the small diameter of said casing being less than the diameter of said bottle, to resiliently retain it on the bottle and the length of said casing being less than the length of said bottle, and unconnected integral substantally trapezoidal flaps hinged on the casing at the upper end thereof and having their lateral edges converging and being of such length that when the casing is applied to said bottle, the adjacent lateral edges of contiguous flaps abut and the free ends of the flaps lie against said bottle neck and in contact therewith at the lower edge of the said flange.
